LAMP-SHADE.

fsrncrniroarrort forming part of Letters Patent No. 693,460, dated February 18, 1902.

Application filed June 24,1901. Serial No. 65,785. on man.)

To all whom it may concern.-

Be it known that LSHIRO TAKABA,a subject of the Emperor of Japan, residing at Boston,- county of Suffolk, State of Massachusetts,

have invented an Improvement in Lamp- Shades, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My invention is an improvement in lampshadesof the kind called Japanese lampshades, in which a light frame is provided with panels or sections of ornamental material, usually of a translucent nature, commonly paper, which is hand-painted or otherwise decorated. Shades of this character have commonly been composed heretofore of a light wooden frame,to which the paper panels have been pasted. Such frames, however, are easily injured and rapidly deteriorate under the influence of the extreme heat from the lamp,

so that they become brittle and easily broken, and also itis difficult topaste the paper panels in place and retain them properly on account of the curvature and materials. Accordingly I have I devised the hereinafter described shade of an exceedingly light and durable character, consisting of a metal frame containing specially-formed ribs, which receive the vertical edges of the panel in interlocked relation in such a manner as to give the shade permanence and stability of shape, while at the same time facilitating its construction and producing a trim and neat appearance.

The constructional details of my invention will be pointed out .more fully in the following description, reference being had to the accompanyin g drawings, in which I have shown a preferred embodiment of the invention, and the latter will be further defined in the appended claims.

In the drawings, Figure 1 represents in side elevation a shade containing my invention,-

parts thereof being broken out for clearness of illustration. Fig. 2 is an enlarged horizontal sectional view taken on the line 2, Fig.

1. Fig. 3 is a transverse vertical section taken on the line 3 3, Fig. 2. Fig. 4 is an enlarged horizontal section taken on the line 4 4, Fig. l.

As herein shown, the frame consists of up per and lower rings a b and vertical ribs 0,

properly bent or arched, .the whole, when of metal, being soldered or otherwise-secured together. These inclose a plurality of panels (1, although it will be understood that I do not restrictmyself in all respects to the details of shape and arrangement shown. The'rihs ssffv c are'preferably of metal capable of being.

rolled inwardly to provide a longitudinal pocket 0 or overhanging retainingflange o for receiving and holdingthe inturned edge d of the adjacent panel. Y

It is difficult to paste a paper panel to a metal rib, and, as already stated, it is difficult to retain the panel'inproper shape and position simply by pasting it or laying it flat against a rib; but by tucking in the edge d of the panel and preferably cementing it in place behind the retaining rib or flange o of the rib, as shown, the panel is secured propstruction being exceedingly strong, neat in appearance, definite and certain in shape and position, and with no possibility of separation of the panels from the ribs or frame. At

their ends the panels and ribs are clamped,

between bands e and the rings, said bands being preferably of some suitable pliable material, pasteboard answering for this purpose in some instances, retaining-pieces 6 being preferably interposed, and the whole held in place by any suitable means, some kind of cement being usually suificient.

The frame being of metal is exceedingly durable, maintaining its vigor and strength notwithstanding the heat to which it is'subjected by the lamp, whereasthe kind having wooden frames gradually became brittle.

The shade is not only strong, but rigid and Very light.

It will be understood that while I prefer to construct the shade precisely as shown, yet I do not limit myself thereto, as many changes may be resorted to within the spirit and scope of my invention, as will be more evident upon reference to the claims.

Having described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. A lampshade, having its shade-surface composed of ribs and panels, a longitudinal pocket being provided in each rib, a longitudinal edge of an adjacent panel being bent into interlocked engagement with the pocket of the adjacent rib, and means applied to said longitudinal edge and distinct from said rib for maintaining said panel and rib permanently in their interlocked relation.

2. A lamp-shade, having its shade-surface composed of ribs and panels, said ribs having longitudinal pockets in their under sides, one longitudinal edge of a panel being bent back on itself and interlocked with the adjacent rib, and a longitudinal edge of the contiguous panel being secured to the back of the panel thus interlocked.

3. i A lamp-shade, having its shade-surface composed of ribs and panels, said ribs having longitudinal pockets in their under sides, one longitudinal edge of a panel being bent back on itself and interlocked with the adjacent rib, a longitudinal edge of the contiguous panel being secured to the back of the panel thus interlocked, and a ring and band, the upper ends of said panels and ribs being clamped between said ring and band.

In testimony whereof have signed my name to this specification in the presence of two subscribing witnesses.
